FOUNTAIN-'SYRINGE.

, Specification of Letters Patent.

Application tiled March 18, 1913. Serial No. 755,352.

To (ZZZ whom it may concern Be it known that I, Lnwrs E. PEAsn, a

a citizen of the United States, residing at syringe with a novel tube support on which the eduction tube-can be sustained. in such a way as to prevent it from becoming broken by having a sharp bend made therein.

In common practice fountain syringes are hung from a hook or nail, and when the syringe is not in use the eduction tube is frequently hung up over thesupporting hook or nail. When this is done a sharp bond is given to the tube whereit engages the nail, which very soon breaks or cracks it at this point.

My invention aims to obviate this difliculty by providing a tube support which will hold the tube in such a way that there will be no danger of its becoming broken or injured.

In the drawings wherein I have shown some preferred embodiments of my inven tion, Figure 1 is a view of a fountain syringe embodying the invention showing the manner in which the tube is supported by the tube support; Fig. 2 is an enlarged section on the line m-a, Fig. 1; Fig. 3 is a view similar to Fig. 2, but showing a different em bodiment of the invention.

1 designates the bag or water-containing receptacle of the fountain syringe, and 2 the usual eduction tube which is provided with the shut-off 3 and a removable tip 4 as usual. These parts are such as are usually found in fountain syringes and form no part of my present invention.

My syringe is formed with a tube support shown generally at 5 which is of such shape and dimensions as to support the tube 2 without forming a sharp bend. therein. This tube support is preferably associated with the supporting tab 6 with which fountain syringes are usually provided and by which they are sustained. The tube support may be either made integral with the tab or may be a separate part secured thereto. In Fig. 2 I have shown it as integral with the tab,

said tab being molded to present the boss or thickened portion 5 which is preferably circular in shape and is provided on its periphery with a tubereceiving groove 7 of a size to receive the tube 2, as clearly shown in Fig. 2. The tube support 5 and tab 6 are provided with an aperture 8 to receive the hook, nail or other supporting device for the syringe, and I will preferably provide this aperture with a metal lining which can be done by inserting an eyelet 9 therein of the proper shape? This eyelet is provided with the flange 10 which embraces the front face of the tube support and with the flange 11 on the other end which overlies and embraces a washer or grommet 12. The eyelet 9 serves not only to provide a metal lining for the aperture 8, but it also serves as a reinforcing means for the tube support 5 and serves to hold the tube support in its proper shape.

In Fig. 3 the tube support 50 is separate from the tab 6, it being in the nature of a filling of rubber or other material which is applied to the face of the tab 6 and is held thereto by the eyelet 9, said eyelet having the same construction as that described with reference to Fig. 2. The construction shown in Fig. 3 makes it possible to apply my im proved tube support to any ordinary fountain which is provided with the supporting tab 6. This can be done by merely providing the filling piece :30 of the proper shape and securing it to the tabby the eyelet 9.

One advantage of making the tube support in connection with the supporting tab 6 is that when the tube 2 is resting on the support the end of the tube can be placed within the bag 1, thus avoiding all danger of dripping.

While I have illustrated some embodiments of my invention, I do not wish to be limited to the constructional details shown. Having fully described my invention what E claim as new and desire to secure by Letters Patent is:

1. In a fountain syringe, the combination with a bag and an eduction tube connected Patented Apr. lat, 191 i.

thereto, said bag having a supporting tab at its upper end, of a tube support on said tab, said tab and support having an aperture extending therethrough to receive a hook or other supporting means.

3. In a fountain syringe, the combination With a bag and an eduction tube connected thereto, said bag having a supporting tab at its upper end, of a tube support on said tab, said tab and support having a metallined aperture extending therethrough to receive a hook or other supporting means.

4. .In a fountain syringe, the combination with a bag and an .eduction tube connected thereto, said bag having a supporting tab at its upper end, of a tube support on said tab, said tab andvsupport having an aperture extending therethrough to receive a hook or other supporting means, and a metal eyelet lining said aperture and provided with a flange which embraces the tube support and holds it in the desired shape.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
